Download the latest version of AGL : https://download.automotivelinux.org/AGL/release/octopus/latest/raspberrypi4/deploy/images/raspberrypi4-64/
(This version is referred to as the release version.)
I ran the image on Raspberry Pi 4 and found a bug in the mediaplayer.
The MDP version used by AGL is 0.23.6, but as a result of checking the source of the latest version, 0.23.11, it seems that the corresponding part is not patched.
After creating a malicious MP3 file, I used a USB to play the media file on AGL.
Then, AGL caused a crash for mediaplayer (coredump).
I checked this crash using journalctl.
After that in AGL, MEDIAPLAYER does not work again (no response when pressed, Absence of watchdog).
I will attach different files that cause the crash.
Check it out and let me know.
